Abstract
n-Hexyl isocyanate and n-octyl isocyanate were synthesized in toluene by the reactions of bis(trichloromethyl)carbonate and n-hexyl or n-octyl amine,respectively.After removement of toluene by air distillition in the present of calcium hydride,n-hexyl or n-octyl isocyanates were obtained by reduced pressure distillation.n-Hexyl or n-octyl isocyanates were of purity 99.0% in 72.5% and 78.9% yield,respectively.
